Yes, it does.
"Mid-grade" Fuel

That won't work everywhere. I have yet to see E85 anywhere in the region I live and work in. Even Quick Trips and Race Tracks don't have E85 here.
Also, our octane ratings are different. Our "regular" is 87 and our "premium" is 93. I haul a good bit of "90 Rec" gas which is basically the 90 octane base stock without ethanol added. I even have 1 store that sells 87 ethanol free...which gets a blend of 84 octane and 90 octane base stock to make 87.
I have yet to not see e85
The ethanol mixed in your gas comes from somewhere even if it’s 99% denatured
Further 91e0 + 10% ethanol =93e10
my guess is standardization in the industry would reduce cost by increasing the duration of a pipe run
93 is rare in Wisconsin and always e10
91 can be either e0 or e10
E15 seems to be everywhere
I'm totally aware where the ethanol comes from since I drive a fuel tanker. It's loaded/mixed as the product is loaded onto the trailer for transport.
Here, 90 octane CBOB (Conventional Blendstock for Oxygenate Blending) + 10% 111 octane ethanol = 93e10 gasoline. 84 Octane CBOB + 10 % 111 octane ethanol = 87e10. The 2 terminals (Kinder-Morgan and Transmontaigne) where I load do not even have e15 or e85 gas set up to load in the system.
So if there's only two fill ports they must be blending?
No I'm sure 89 does, but I get better mpg on the premium in my Passat, so I suspect the premium has significantly less ethanol. If they are blending it I figure the 89 to have less than the 87 then.
I've used the 89 PON exclusively for some years. Nearly all blender pump products. Prior to about the late 70's, regular gas was 89. Very low engine compressions in the mid 70' and 80's gave birth to the '' economy" grade 87. I had used premium fuel in most cars for decades but the cost spread is too much today. If you have a car with fairly wide parameters in timing advance from the knock sensor control, premium fuel mileage can be much better. That was my experience with several Nissans in the 90's and '00's. Supposedly, the majority of new vehicles sold in recent years require or strongly recommend 91 PON or higher.
They're blending 87e10 and 93e10....then you are getting 89e10. They all have the same ethanol content. The same is true if I load mid-grade on my trailer. If I preset the meter for 1000 gallons, the 1st 100 gallons is pure ethanol. The other 900 gallons is a blend of 84 and 90 CBOB.
I would probably use 89 more often if it weren't such a price jump. All the big name stations in my area are something like this:
87 $3.95
89 $4.15
91 $4.25
So the first two octane points cost $0.20/gallon and the second two octane points are $0.10/gallon. I only run premium in the sports car.
Also, the OP hasn't posted back since their first post... I wonder if they are reading all this.

They blend in my neck of the woods. The majority of stations have three tank caps visible.
I'm assuming that one is 87-e10, another is 93-e10, the last is diesel. The pumps have four buttons. 88, 89, 93, and a second nozzle with the last button, diesel.
They've gotta be mixing the go go juice for the mid-grade gasoline. But here's a thought...
Premium fuel sells slower than regular. If a pump mixed premium and regular to derive mid- grade, are your chances of getting older fuel greater if you buy mid- grade?

A few stations here sell 87 E10, 87 E0, and 91 E0. They call the pure 87 a "mid grade", and others skip it all together and just sell the ethanol 87 and pure 91 only. The former would indicate no mixing on any of the grades and 3 separate tanks.
I don’t generally worry about it… between more and more cars requiring premium, and the fact that people will put high octane gas into vehicles that don’t require it for whatever reason, the stations will go through their premium deliveries relatively quickly. Just pick a busy station and all should be good.They blend in my neck of the woods. The majority of stations have three tank caps visible.

Just joining the conversation here, I usually "mix my own" 87 and maybe
2.5 gallons of 93 to make a mid-grade. This is a pain.
I will look for the coloured lids and count. Most stations I frequent have 3 gasoline grade plus
low sulphur diesel. So with three lids I'm good to buy from the 89 blending pump!
now my concern is that it works and blends properly!

Ja, I do just that. A highway side shell station decently available delivers 93 V-power Nitro+.
I've tried other brand premium fuel but they make the sport tuned SS truck sluuuuuuuggish. So far this place hasn't set me wrong.
But let me tell you a story of little sister pumping a 75% tank of water from a Racetrack just a few more miles yonder...
$1200 later, all 16 Hemi plugs and a fuel disposal fee atop of that latter + oil change at the Jeep/FCA store... she shops fuel at the same places I do. Like you said, grab a gulp of gas at stations that are busy and turn over stock quickly.
